Answer:
x = 3
Hope this helps!
Step-by-step explanation:
ΔABC is a 45°, 45°, 90° triangle. The longest side ( 6
) can be 
while AB and CB are x. Because 6 is equal to , you can see that x is equal to 6. Both AB and CB are equal to 6. ΔBDC ( CDB ) is a right triangle ( 30°, 60°, 90° ) so, BD = x, CB = 2x, and CD = 
. CB is equal to 6 so 2x = 6, x = 3.

Answer:
b) dV/dt = c * dT/dt
Step-by-step explanation:
Differentiating the equation with respect to time, you have ...
V = cT
dV/dt = c·dT/dt . . . . matches choice B
Answer:A)33m
B)32.86m/s
Step-by-step explanation:
Using the equation of motion
V^2=U^2-2aS
Where V=final velocity of the car=0
U=initial velocity=17m/s
a=deceleration=-12m/s^2
S= distance covered by car before stopping
Substituting into the equation
0=17^2-2×12×S
0=289-24S
24S=289
S=289/24
S=12m.
The distance between the car and the deer=45-12=33m
B) Using same equation
Distance,S is now 45m,which is the distance between the car and the deer.while deceleration remains same
V^2=U^2-2aS
0=U^2-2×12×45
U^2=1080
U=√1080
U=32.86m/s
As the sample size, "n", increases, the standard error of the mean becomes SMALLER.
